[0003] Considering network energy conservation, supporting on-demand transmission of System Information Block 1 (SIB 1) for idle and / or inactive terminals, also known as User Equipment (UE), is a key candidate for time-domain network energy conservation. For example, when network devices need to save energy, they can achieve this by not sending SIB 1. However, there is currently no solution for waking up network devices to send SIB 1 when energy conservation is required. Summary of the Invention

[0133] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0134] The following is an introduction to the relevant technologies involved in this disclosure:

[0135] 1. Network energy saving

[0136] Energy consumption is a key indicator of operators' operating expenses (OPEX). In mobile networks, energy consumption accounts for 23% of total OPEX, with the vast majority of this energy consumption coming from the radio access network, particularly the active antenna unit (AAU). Currently, 5G networks consume approximately two to three times more energy than fourth-generation (4G) networks, making energy-saving technologies for 5G networks even more crucial.

[0137] Network energy conservation primarily discusses various technologies that help reduce energy consumption in network devices from the perspectives of time, frequency, spatial, and power domains. Specifically, for network energy conservation purposes, a cell can transmit only the Synchronization Signal Block (SSB) and not SIB1. This reduced SIB1 transmission reduces network energy consumption.

[0138] 2. Random access process

[0139] The random access procedure includes a two-step random access procedure and a four-step random access procedure; wherein, the four-step random access procedure includes: the UE sends a random access preamble (preamble) on the PRACH resource, that is, the first message of the random access procedure or called message 1 (Msg1); the UE receives a random access response (Random Access Response, RAR) message on the PDCCH, that is, the second message of the random access procedure or called message 2 (Msg2); the UE sends the third message of the random access procedure, or called message 3 (Msg3) on the physical uplink shared channel (PUSCH); the UE receives a contention resolution message on the physical downlink shared channel (PDSCH), that is, the fourth message of the random access procedure or called message 4 (Msg4).

[0140] The UE obtains the specific configuration of the random access opportunity (RACH occasion, RO) by decoding the SIB signaling sent by the base station in the current cell, and initiates contention-based random access (CBRA) to the cell it is currently residing in. That is, it sends a preamble based on the ZC (Zadoff-Chu) sequence to the base station on the RO. Before sending the preamble, the UE has already determined the associated SSB. The transmit beam of the associated SSB is the best candidate for determining the base station's receive beam. However, the base station side does not know the associated SSB corresponding to the preamble sent by the terminal.

[0141] The solution is to establish an association between RO subsets, preambles, and SSBs. After a UE detects an SSB, it selects an RO and preamble from the RO subset and preamble associated with that SSB. The RO and preamble selected by the UE implicitly indicate the SSB detected by the UE. When the base station detects a specific preamble on a specific PRACH resource, it can use the transmit beam of the associated SSB to determine the receive beam.

[0142] The association period of SSB mapping to RO is defined as: at least one round of SSB to RO mapping is completed within the period, so that each actually transmitted SSB is mapped to at least one RO. The association period of SSB mapping to RO must be an integer multiple of the PRACH configuration period, and the multiple can be the minimum value among the values ​​listed in Table 1 below. The association period is calculated from system frame 0. After completing one round of SSB to RO mapping within an association period, the next round of mapping continues until the remaining ROs are insufficient to complete one round of SSB to RO mapping. If the remaining ROs are insufficient to complete one round of SSB to RO mapping, these remaining ROs are an invalid RO set. All ROs in the invalid RO set cannot be associated with SSB and cannot be used for PRACH transmission. Since the number of valid ROs contained in an association period of SSB mapping to RO is variable under some configuration conditions, it is considered to define the time domain repetition period of the association period of SSB mapping to RO by the association pattern period. The maximum value of the association pattern period of SSB mapping to RO is 160 milliseconds.

[0143] Table 1: Correspondence between PRACH configuration period and SSB mapping to RO association period

[0144] The association relationship between SSB and RO supports 1-to-1, many-to-1, and 1-to-many situations. The specific mapping rules are as follows: The UE reads the high-level parameters and obtains two parameters, N and R. Among them, N represents the number of SSBs associated with a RO; R represents the number of consecutive preambles based on contention-based random access corresponding to each SSB. For CBRA, the order of mapping SSB index to RO index is as follows:

[0145] First, sort in ascending order of preamble index within a RO;

[0146] Second, the frequency resource indexes of multiple frequency-division-multiplexed ROs are arranged in ascending order;

[0147] Third, arrange them in increasing order of the time resource index of the time division multiplexing RO within a PRACH time slot;

[0148] Fourth, arrange in ascending order of PRACH time slot index.

[0149] The embodiments of the present disclosure provide an information processing method, terminal, and network device to address the current lack of a solution for waking up a network device to send SIB 1. The method and terminal (or network device) are based on the same disclosed concept. Since the principles of solving the problem are similar, the implementation of the method and terminal (or network device) can refer to each other, and repeated parts will not be repeated.

[0150] As shown in FIG1 , an embodiment of the present disclosure provides an information processing method, comprising the following steps:

[0151] Step 11: The terminal sends first information to the network device; wherein the first information is used to request the network device to send SIB 1, and / or the first information is used to indicate the RRC state that the terminal expects or requests to be in the first cell.

[0152] In some embodiments, the first cell may be a cell covered by the network device. For example, the terminal sending the first information to the network device includes: the terminal sending the first information to the first cell. For example, the first cell may be an energy-saving cell (ie, the first cell does not actively send SIB 1).

[0153] In some embodiments, the first cell may also be a cell covered by a network device other than the network device, for example, a terminal sends first information to the network device, and the network device sends the first information to the first cell (or the network device where the first cell is located). For example, the first cell may be an energy-saving cell (i.e., the first cell does not actively send SIB 1).

[0154] In some embodiments, the first information can be used to request the network device to send SIB 1. For example, if the first cell is an energy-saving cell and the terminal has data transmission or other needs, the first information can be sent to the network device to wake up the network device to send SIB 1 (or trigger the sending of SIB 1).

[0155] In some embodiments, the first information may be used to indicate an RRC state that the terminal desires or requests to be in the first cell, where the RRC state includes but is not limited to at least one of the following: a connected state, an idle state, an inactive state, etc. For example, when the terminal is currently in an idle state or an inactive state and desires to access the first cell, the terminal may send the first information to notify the network device of its request to access the first cell (i.e., its desire to be in a connected state in the first cell).

[0156] In some embodiments, the first information may also be used to request the network device to send SIB 1 and to indicate the RRC state that the terminal expects or requests to be in the first cell. For example, if the first cell is an energy-saving cell and the terminal has data transmission or other requirements, but is currently in an idle state or an inactive state, the terminal may send the first information to the network device to notify the network device that it expects to access the first cell and to wake up the network device to send SIB 1 (or trigger the sending of SIB 1).

[0157] In the above scheme, the terminal is supported to actively send the first information to the network device; wherein, the first information is used to request the network device to send SIB 1, and / or, the first information is used to indicate that the terminal expects or requests the RRC state in the first cell. In this way, for energy-saving cells, the terminal can request to wake up the network device to send SIB 1 or trigger the sending of SIB 1, and / or notify the network device of the terminal's access request or residence request, etc., which can reduce the delay for the terminal to enter the connected state and reduce signaling overhead.

[0158] In some embodiments, the first information includes a random access preamble; and / or the first information is carried in Msg A and / or Msg 3.

[0159] For example, the first information includes a random access preamble, or is referred to as the first information carried in the first message (Msg1) of the random access process, and is also used through the random access preamble to request the network device to send SIB 1 and / or indicate that the terminal expects or requests the RRC state in the first cell. For example: the terminal may have a transmission requirement (such as transmitting uplink data and / or downlink data), and expects to enter the connected state through the random access process on the first cell to transmit data. The random access preamble in the random access process can be used to request the network device to send SIB 1 and / or indicate that the terminal expects or requests the RRC state in the first cell (for example: the terminal expects to be in a connected state in the first cell, or the terminal expects to access the first cell for data transmission).

[0160] For another example, the first information can be carried in Msg A, that is, the first message in the two-step random access process (2-step RA), including the transmission of preamble and PUSCH. For example: the preamble (that is, the first information) sent in the Msg A can be used to request the network device to send SIB 1 and / or indicate that the terminal expects or requests the RRC state in the first cell. For example: the terminal may have a transmission requirement (such as transmitting uplink data and / or downlink data), and expects to enter the connected state through a random access process on the first cell to transmit data. Then, Msg A in the 2-step RA process can be used to request the network device to send SIB 1 and / or indicate that the terminal expects or requests the RRC state in the first cell (for example: the terminal expects to be in a connected state in the first cell, or the terminal expects to access the first cell for data transmission).

[0161] For another example, the first information can be carried in Msg 3, which is the third message in the four-step random access process (4-step RA). For example, the first information carried in the Msg 3 can be used to request the network device to send SIB 1 and / or indicate that the terminal expects or requests the RRC state in the first cell. For example, the terminal may have a transmission requirement (such as transmitting uplink data and / or downlink data) and expects to enter the connected state through a random access process on the first cell to transmit data. Then, Msg 3 in the random access process can be used to request the network device to send SIB 1 and / or indicate that the terminal expects or requests the RRC state in the first cell (for example, the terminal expects to be in a connected state in the first cell, or the terminal expects to access the first cell for data transmission).

[0162] In this embodiment, the signaling overhead can be reduced by carrying the first information in Msg1 (or preamble) or Msg A or Msg 3 in the random access process to request the network device to send SIB 1 and / or indicate that the terminal expects or requests the RRC state in the first cell.

[0163] In some embodiments, when the random access preamble (such as Msg 1) indicates that the terminal expects or requests the RRC state in the first cell, the first information carried by the Msg 3 is used to request the network device to send SIB 1.

[0164] In this embodiment, the network device is notified of the terminal's expectation or request for the RRC state in the first cell through Msg 1 (or preamble) in the random access process, and the network device can also be requested to send SIB 1, etc. through Msg 3 in the random access process, which can reduce signaling overhead.

[0165] In some embodiments, the terminal sending the first information to the network device includes:

[0166] The terminal sends the random access preamble to the network device on the first resource and / or the second resource;

[0167] The first resource is a PRACH resource related to the terminal's expectation or request to be in the first RRC state in the first cell; for example, the first resource is a PRACH resource, and when the terminal sends a random access preamble on the first resource, the resource is used to indicate that the terminal requests the network device to send SIB 1 and / or indicates that the terminal expects or requests to be in the first RRC state in the first cell. Alternatively, the first resource is used by the terminal to request the network device to send SIB 1 and / or to indicate that the terminal expects to be in the first RRC state in the first cell.

[0168] The second resource is a PRACH resource related to the terminal's desire to be in the second RRC state in the first cell. For example, the second resource is a PRACH resource, and when the terminal sends a random access preamble on the second resource, the resource is used to indicate that the terminal requests the network device to send SIB 1 and / or indicates that the terminal desires or requests to be in the second RRC state in the first cell. Alternatively, the second resource is used by the terminal to request the network device to send SIB 1 and / or to indicate that the terminal desires to be in the second RRC state in the first cell.

[0169] In some embodiments, the first RRC state includes: a connected state; and / or the second RRC state includes: an idle state and / or an inactive state.

[0170] For example, if a terminal sends first information (such as a preamble) on a first resource, then after receiving the first information on the first resource, the network device may be triggered to send SIB 1, and the network device may learn that the terminal expects to be in a connected state in the first cell, or learn that the terminal expects to access the first cell, so that the network device may send a TA estimated or determined based on the first information. This can reduce the terminal from sending the preamble again to estimate the TA, thereby reducing signaling overhead and reducing the delay for the terminal to enter the connected state.

[0171] For another example, the terminal sends the first information on the second resource. After the network device receives the first information on the first resource, it can trigger the network device to send SIB 1, and the network device can know that the terminal expects to be in an idle state and / or an inactive state in the first cell, or learn that the terminal wants to reside in the first cell, so that the network device can send a reference signal for terminal measurement, or send a paging message, etc. The embodiment of the present disclosure is not limited to this. This can reduce the terminal sending request signaling again, thereby reducing signaling overhead.

[0172] In some embodiments, after the terminal sends the first information to the network device, the method further includes at least one of the following:

[0173] The terminal performs a first operation; wherein the first operation includes monitoring a PDCCH that schedules the SIB 1; and / or receiving the SIB 1 sent by a network device;

[0174] The terminal performs a second operation, wherein the second operation includes: receiving a timing advance TA sent by a network device, and / or receiving feedback information from the network device in response to the first information.

[0175] For example, a terminal sends first information on a first resource, where the first resource is a PRACH resource related to the terminal's desire or request to be in an RRC connected state in the first cell. After sending the first information on the first resource, the terminal may perform the following first operation: monitoring a PDCCH that schedules the SIB 1; and / or receiving the SIB 1 sent by a network device.

[0176] For example, after the terminal sends the first information to the network device, the first operation may be performed. The specific process may be one of the following:

[0177] Process A1: The terminal sends a preamble → the network device sends the scheduling information of SIB 1 and / or sends SIB 1 on the PDCCH (correspondingly, the terminal monitors the PDCCH that schedules the SIB 1 and / or receives the SIB 1) → the network device sends a RAR message (correspondingly, the terminal receives the RAR message) → the terminal sends Msg3 → the network device sends Msg4 (correspondingly, the terminal receives Msg4).

[0178] Process A2: The terminal sends a preamble → the network device sends a RAR message (correspondingly, the terminal receives the RAR message) → the network device sends the scheduling information of SIB 1 on the PDCCH and / or sends SIB 1 (correspondingly, the terminal monitors the PDCCH that schedules the SIB 1 and / or receives the SIB 1) → the terminal sends Msg3 → the network device sends Msg4 (correspondingly, the terminal receives Msg4).

[0179] Process A3: The terminal sends a preamble → the network device sends a RAR message (correspondingly, the terminal receives the RAR message) → the terminal sends Msg3 → the network device sends the scheduling information of SIB 1 on PDCCH and / or sends SIB 1 (correspondingly, the terminal monitors the PDCCH that schedules the SIB 1 and / or receives the SIB 1) → the network device sends Msg4 (correspondingly, the terminal receives Msg4).

[0180] Process A4: The terminal sends a preamble → the network device sends a RAR message (correspondingly, the terminal receives the RAR message) → the terminal sends Msg3 → the network device sends Msg4 (correspondingly, the terminal receives Msg4) → the network device sends the scheduling information of SIB 1 and / or sends SIB 1 on PDCCH (correspondingly, the terminal monitors the PDCCH that schedules the SIB 1 and / or receives the SIB 1).

[0181] For example, a terminal sends first information on a first resource, where the first resource is a PRACH resource related to the terminal's desire or request to be in an RRC connected state in the first cell. After sending the first information on the first resource, the terminal may perform the following second operation: receive a timing advance (TA) sent by a network device, and / or receive feedback information from the network device regarding the first information.

[0182] In some embodiments, the TA and / or the feedback information are carried in a random access response message sent by the network device; or the feedback information is received by the terminal before receiving the random access response message. That is, after sending the first information, the terminal may perform the following second operation: receiving a random access response message; or, after sending the first information, the terminal may perform the following second operation: receiving the feedback information. The feedback information may be used to indicate whether the network device sends SIB 1 and / or whether to allow the terminal to expect operations related to being in an RRC state in the first cell.

[0183] For example, taking the feedback information instructing the network device not to send SIB 1 as an example, after the terminal sends the first information to the network device, the second operation can be performed. The specific process can be one of the following:

[0184] Process B1: The terminal sends a preamble → the network device sends an RAR message (carrying the feedback information, indicating that the network device does not send SIB 1 and / or whether to allow the terminal to expect to be in the RRC state in the first cell), and the process ends. In some embodiments, the terminal may attempt to access other cells, etc., but the embodiments of the present disclosure are not limited to this.

[0185] Process B2: The terminal sends a preamble → the network device feeds back information indicating that the network device does not send SIB 1 and / or whether to allow the terminal to operate in the RRC state in the first cell, and the process ends. In some embodiments, the terminal may attempt to access other cells, etc., but the embodiments of the present disclosure are not limited to this.

[0186] It should be noted that after the terminal sends the preamble, if the network device does not send feedback information, the network device may not execute the scheduling information of SIB 1 and / or send SIB 1 on the PDCCH. The corresponding terminal can try to monitor the PDCCH that schedules the SIB 1 and / or receive the SIB 1. If the scheduling information of SIB 1 is not monitored and / or SIB 1 is not received within a period of time, the process ends, or the terminal may also try to access other cells, etc. The embodiments of the present disclosure are not limited to this.

[0187] In some embodiments, the duration for which the terminal attempts to monitor the PDCCH that schedules the SIB 1 and / or receive the SIB 1 may be configured by a network device or based on a protocol agreement, or depend on terminal implementation, etc., and the embodiments of the present disclosure are not limited thereto.

[0188] In some embodiments, the terminal performs the first operation and the second operation, including:

[0189] The terminal receives feedback information sent by the network device;

[0190] In a case where the feedback information indicates that the network device confirms sending the SIB1, the terminal monitors the PDCCH that schedules the SIB1 and / or receives the SIB1 sent by the network device.

[0191] For another example, after the terminal sends the first information to the network device, it performs the second operation, such as receiving feedback information sent by the network device (which may be carried in the random access response message, or may be independent of the random access response message), for example, the feedback information may indicate that the network device confirms the sending of SIB 1 and / or allows the terminal to expect to be in the RRC state in the first cell, etc., and the terminal may continue to perform the first operation. The specific process may be one of the following:

[0192] Process C1: The terminal sends a preamble (the network device can estimate the TA based on the preamble) → the network device sends a RAR message (correspondingly, the terminal receives the RAR message, carrying feedback information and / or TA) → the network device sends the scheduling information of SIB 1 on the PDCCH and / or sends SIB 1 (correspondingly, the terminal monitors the PDCCH that schedules the SIB 1 and / or receives the SIB 1) → the terminal sends Msg3 → the network device sends Msg4 (correspondingly, the terminal receives Msg4).

[0193] Process C2: The terminal sends a preamble (the network device can estimate the TA based on the preamble) → the network device sends feedback information (correspondingly, the terminal receives the feedback information) → the network device sends the scheduling information of SIB 1 on the PDCCH and / or sends SIB 1 (correspondingly, the terminal monitors the PDCCH that schedules the SIB 1 and / or receives the SIB 1) → the network device sends a RAR message (correspondingly, the terminal receives the RAR message, carrying TA) → the terminal sends Msg3 → the network device sends Msg4 (correspondingly, the terminal receives Msg4).

[0194] In some embodiments, after the terminal receives the SIB 1 sent by the network device, the method further includes at least one of the following:

[0195] The terminal receives a random access response message sent by the network device;

[0196] The terminal sends Msg 3 to the network device;

[0197] The terminal performs an operation related to the first cell being in the second RRC state.

[0198] For example, the terminal may learn from other cells whether the first cell allows the terminal to access or camp on (for example, by receiving the second indication information sent by the second cell), specifically:

[0199] Before the terminal sends the first information to the network device, the method further includes:

[0200] The terminal receives second indication information sent by the second cell; wherein the second indication information is used to indicate whether the terminal is allowed to access the first cell; in some embodiments, the second cell may be a non-energy-saving cell, and the second indication information may be carried in a broadcast message, such as SIBx.

[0201] The terminal sending first information to the network device includes:

[0202] If the second indication information indicates that the terminal is allowed to access the first cell, the terminal sends the first information to the network device.

[0203] For example: when the terminal learns through other cells that the first cell allows the terminal to access or allows the terminal to reside, the terminal can perform the corresponding access operation (or operation related to the terminal being in the first RRC state in the first cell) after receiving SIB 1 sent by the network device: the terminal receives the random access response message sent by the network device; and / or the terminal sends Msg 3 to the network device (i.e., continues to perform the random access process); or performs operations related to the first cell being in the second RRC state, such as: cell selection or reselection, radio resource management (RRM) measurement, monitoring paging messages or other operations related to the second RRC state, etc. The embodiments of the present disclosure are not limited to this.

[0204] For another example, the terminal defaults to the terminal receiving the SIB 1 sent by the network device, that is, it can access the first cell or reside in the first cell. For example: the first information sent by the terminal indicates that the terminal expects or requests to be in the first RRC state in the first cell, then after receiving the SIB 1 sent by the network device, the terminal can perform a corresponding access operation (or an operation related to the terminal being in the first RRC state in the first cell): the terminal receives a random access response message sent by the network device; and / or the terminal sends Msg 3 to the network device (i.e., continues to perform the random access process); for another example: the first information sent by the terminal indicates that the terminal expects or requests to be in the second RRC state in the first cell, then after receiving the SIB 1 sent by the network device, the terminal can perform operations related to the first cell being in the second RRC state, such as: cell selection or reselection, RRM measurement, monitoring paging messages or other operations related to the second RRC state, etc. The embodiments of the present disclosure are not limited to this.

[0205] In some embodiments, the SIB 1 sent by the network device carries first indication information; wherein the first indication information is used to indicate whether the terminal is allowed to access the first cell, and / or the first indication information is used to indicate the RRC state that the terminal is allowed to be in in the first cell;

[0206] When the first indication information indicates that the terminal is allowed to access the first cell, the terminal performs at least one of the following:

[0207] receiving a random access response message sent by the network device;

[0208] Sending Msg 3 to the network device;

[0209] An operation related to the first cell being in the second RRC state is performed.

[0210] For example, whether the first cell allows the terminal to access and / or indicates the RRC state that the terminal is allowed to be in in the first cell, etc., if the terminal is not notified through other cells, the network device can carry the first indication information in the SIB 1 sent to the terminal, which is used to indicate whether the terminal is allowed to access the first cell, and / or the first indication information is used to indicate the RRC state that the terminal is allowed to be in in the first cell (for example, allowing the terminal to be in a connected state in the first cell, or allowing the terminal to be in an inactive state and / or idle state in the first cell, etc.).

[0211] For example, if the first indication information indicates that the terminal is allowed to access, the operations that the terminal may perform include: operations related to the terminal being in a first RRC state in the first cell, and / or operations related to the terminal being in a second RRC state in the first cell. For example, operations related to the terminal being in the first RRC state in the first cell include the terminal receiving, by the terminal, a random access response message sent by the network device; and / or the terminal sending Msg 3 to the network device (i.e., continuing the random access process).

[0212] For another example: the first indication information indicates that the terminal is allowed to access, and indicates that the terminal is allowed to be in a connected state in the first cell, then the terminal can perform the corresponding access operation (or operation related to the terminal being in the first RRC state in the first cell): the terminal receives the random access response message sent by the network device; and / or the terminal sends Msg 3 to the network device (i.e., continues to perform the random access process).

[0213] For another example: the first indication information allows access to the terminal, and indicates that the terminal is allowed to be in an inactive state and / or idle state in the first cell, then the terminal can perform operations related to the second RRC state in the first cell, such as: cell selection or reselection, RRM measurement, monitoring paging messages or other operations related to the second RRC state, etc. The embodiments of the present disclosure are not limited to this.

[0214] For another example, if the first indication information indicates that the terminal is not allowed to access, the process ends, or the terminal may try to access other cells, etc., but the embodiments of the present disclosure are not limited thereto.

[0215] In some embodiments, the first indication information is further used to indicate at least one of the following:

[0216] The terminal receives the random access response message sent by the network device;

[0217] The terminal sends Msg3 to the network device;

[0218] The terminal performs operations related to the first cell being in the second RRC state.

[0219] In some embodiments, the terminal sends first information to the network device on a second resource; wherein the second resource is a PRACH resource related to the terminal's expectation or request to be in an RRC idle state and / or an RRC inactive state in the first cell.

[0220] For example: the terminal may not have data transmission requirements (for example, the terminal does not need to transmit uplink data and / or downlink data), but the terminal expects to reside in the first cell, for example, the terminal may perform cell selection or reselection, monitor paging messages, perform RRM measurements, etc. At this time, the terminal can send the first information on the second resource to request the network device to send SIB 1 and / or notify the network device that it expects to be in the idle state and / or inactive state in the first cell, but the terminal does not enter the connected state and performs idle state operations. The specific process includes one of the following:

[0221] Process D1: The terminal sends first information→the terminal receives SIB 1.

[0222] Process D2: the terminal sends the first information→the terminal receives feedback information (for example, the feedback information indicates that the network device confirms sending SIB 1)→the terminal receives SIB 1.

[0223] Process D3: the terminal sends the first information → the terminal receives feedback information (for example, the feedback information instructs the network device not to send SIB 1), and the process ends.

[0224] In some embodiments, the terminal sends the random access preamble to the network device on the first resource and / or the second resource, including at least one of the following:

[0225] The terminal sends a first random access preamble code to the network device on a first resource;

[0226] The terminal sends a second random access preamble code to the network device on a second resource.

[0227] The first random access preamble and the second random access preamble may be the same or different; or the time domain resources and / or frequency domain resources corresponding to the first resource and the second resource may also be the same or different.

[0228] For example, the first random access preamble code and the second random access preamble code may be the same, and the time domain resources and / or frequency domain resources corresponding to the first resource and the second resource are different; or, the first random access preamble code and the second random access preamble code are different, and the time domain resources and / or frequency domain resources corresponding to the first resource and the second resource may be the same or different.

[0229] In some embodiments, the first random access preamble is determined by a first index value, and the second random access preamble is determined by a second index value; wherein, when the time domain resources and / or frequency domain resources corresponding to the first resource and the second resource are different, the first index value may be equal to the second index value; or, when the time domain resources and / or frequency domain resources corresponding to the first resource and the second resource are the same or different, the first index value is not equal to the second index value.

[0230] For example, the first index value may be random access preamble start index 1 (ra-PreambleStartIndex_1), and the second index value may be random access preamble start index 2 (ra-PreambleStartIndex_2). The values ​​of ra-PreambleStartIndex_1 and ra-PreambleStartIndex_2 are different or unequal. The first random access preamble is a preamble sequence determined by ra-PreambleStartIndex_1, and the second random access preamble is a preamble sequence determined by ra-PreambleStartIndex_2.

[0231] Or in some embodiments, the first random access preamble is determined by a first index value, and the second random access preamble is determined by the first index value and a preset rule;

[0232] For example, the first index value may be ra-PreambleStartIndex_1, which is used to determine the sequence of the first random access preamble code. The first random access preamble code is a preamble sequence determined by ra-PreambleStartIndex_1; the second random access preamble code is a preamble sequence determined by ra-PreambleStartIndex_1 and a predefined rule. For example, the predefined rule is that the preamble sequence corresponding to the second random access preamble code is the sequence corresponding to ra-PreambleStartIndex_1+N, or it may be other rules, etc. The embodiments of the present disclosure are not limited to this.

[0233] Or in some embodiments, the second random access preamble is determined by a second index value, and the first random access preamble is determined by the second index value and a preset rule;

[0234] For example, the second index value may be ra-PreambleStartIndex_2, which is used to determine the sequence of the second random access preamble. The second random access preamble is a preamble sequence determined by ra-PreambleStartIndex_2. The first random access preamble is a preamble sequence determined by ra-PreambleStartIndex_2 and a predefined rule. For example, the predefined rule is that the preamble sequence corresponding to the first random access preamble is the sequence corresponding to ra-PreambleStartIndex_2+N, or it may be other rules, etc. The embodiments of the present disclosure are not limited to this.

[0235] Alternatively, in some embodiments, the first random access preamble is determined by a first index value, and the second random access preamble is determined by the first index value and a first parameter.

[0236] For example, the first index value may be ra-PreambleStartIndex_1, which is used to determine the sequence of the first random access preamble code. The first random access preamble code is a preamble sequence determined by ra-PreambleStartIndex_1; the second random access preamble code is a preamble sequence determined by ra-PreambleStartIndex_1 and the first parameter. For example, the preamble sequence corresponding to the second random access preamble code is the sequence corresponding to ra-PreambleStartIndex_1+N, or other rules may be used, where N is determined by the first parameter, or N is the first parameter, etc. The embodiments of the present disclosure are not limited to this.

[0237] Alternatively, in some embodiments, the second random access preamble is determined by a second index value, and the first random access preamble is determined by the second index value and a first parameter.

[0238] For example, the second index value may be ra-PreambleStartIndex_2, which is used to determine the sequence of the second random access preamble code. The second random access preamble code is a preamble sequence determined by ra-PreambleStartIndex_2; the first random access preamble code is a preamble sequence determined by ra-PreambleStartIndex_2 and the first parameter. For example, the preamble sequence corresponding to the first random access preamble code is the sequence corresponding to ra-PreambleStartIndex_2+N, or other rules may be used, where N is determined by the first parameter, or N is the first parameter, etc. The embodiments of the present disclosure are not limited to this.

[0239] In some embodiments, at least one of the first index value, the second index value, and the first parameter is configured by a network device;

[0240] Alternatively, at least one of the first index value, the second index value, the preset rule, and the first parameter is agreed upon by a protocol.

[0241] In some embodiments, the first resource and the second resource do not overlap in the time domain (that is, the first resource and the second resource are different time domain resources); and / or, the first resource and the second resource do not overlap in the frequency domain (that is, the first resource and the second resource are different frequency domain resources).

[0242] In some embodiments, the terminal determines the first resource and / or the second resource by at least one of the following methods:

[0243] Mode 1: The first resource corresponds to a first PRACH configuration period in at least two PRACH configuration periods, and / or the second resource corresponds to a second PRACH configuration period in the at least two PRACH configuration periods except the first PRACH period;

[0244] For example: the time domain resource corresponding to the first resource and the time domain resource corresponding to the second resource are different PRACH configuration periods. For example, the network device can configure different PRACH configuration periods for the first resource and the second resource respectively (such as configuring different PRACH configuration period indexes or configuring different parameters for determining the PRACH configuration period).

[0245] Mode 2: The first resource corresponds to a first association period of at least two PRACH association periods, and / or the second resource corresponds to a second association period of the at least two PRACH association periods other than the first association period;

[0246] For example, the time domain resource corresponding to the first resource and the time domain resource corresponding to the second resource have different PRACH association periods. For example, the network device may configure different association periods for the first resource and the second resource, respectively (such as configuring different association period indexes or configuring different parameters for determining the PRACH association period).

[0247] Mode 3: The first resource includes resources corresponding to a first time period in a PRACH configuration period, and / or the second resource includes resources corresponding to a second time period in the PRACH configuration period;

[0248] For example, the time domain resource corresponding to the first resource and the time domain resource corresponding to the second resource are ROs corresponding to different time periods in a PRACH configuration cycle. In some embodiments, the units of the different time periods (i.e., the first time period and / or the second time period) can be at least one of a frame, a subframe, a time slot, etc.; the network device can configure different time periods for the first resource and the second resource, such as configuring at least one of the length of the time period, the start time of the time period, the end time of the time period, and the index of the time period, etc., but the embodiments of the present disclosure are not limited to this.

[0249] In some embodiments, at least one of the first PRACH configuration period, the second PRACH configuration period, the first association period, the second association period, the first time period, and the second time period is configured by a network device;

[0250] Alternatively, at least one of the first PRACH configuration period, the second PRACH configuration period, the first association period, the second association period, the first time period, and the second time period is agreed upon by a protocol.

[0251] In some embodiments, the terminal may determine the first resource and the second resource in the following manner so that the frequency domain resources corresponding to the first resource and the second resource are different (or the first resource and the second resource do not overlap in the frequency domain): the frequency domain resource corresponding to the first resource and the frequency domain resource corresponding to the second resource are ROs on different frequency domain resources, that is, the RO on the frequency domain resource corresponding to the first resource does not overlap with the RO on the frequency domain resource corresponding to the second resource. For example: when the frequency division multiplexing (FDM) resource indication of the resource configured for requesting SIB 1 in the frequency domain is greater than 1, the terminal may select different frequency domain resources for the first resource and the second resource.

[0252] The terminal involved in the embodiments of the present disclosure may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal may also be different. For example, in a 5G system, the terminal may be called User Equipment (UE). A wireless terminal can communicate with one or more core networks (CN) via a radio access network (RAN). A wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal. For example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a radio access network. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and other devices. A wireless terminal may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, or a user device, but is not limited in the embodiments of the present disclosure.

[0253] As shown in FIG2 , an embodiment of the present disclosure provides an information processing method, comprising the following steps:

[0254] Step 21: The network device receives first information sent by the terminal; wherein the first information is used to request the network device to send SIB 1, and / or the first information is used to indicate the RRC state that the terminal expects or requests to be in the first cell.

[0255] In some embodiments, the first information includes a random access preamble; and / or the first information is carried in Msg A and / or Msg 3.

[0256] In some embodiments, when the random access preamble indicates that the terminal expects or requests the RRC state in the first cell, the first information carried by the Msg 3 is used to request the network device to send SIB 1.

[0292] It should be noted that the information processing method on the network device side of the embodiment of the present disclosure and the information processing method on the terminal side are based on the same inventive concept. The two embodiments can refer to each other and can achieve the same technical effect. To avoid repetition, they will not be repeated here.

[0293] The network device involved in the embodiments of the present disclosure may be a base station, which may include multiple cells providing services to terminals. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in an access network that communicates with a wireless terminal through one or more sectors on an air interface, or may be called another name. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present disclosure may be a base transceiver station (BTS) in the Global System for Mobile communications (GSM) or code division multiple access (CDMA), a network device (NodeB) in wide-band code division multiple access (WCDMA), an evolutionary Node B (eNB or e-NodeB) in the long term evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), a home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of the present disclosure. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.

[0294] The information processing method disclosed herein is described below with reference to specific embodiments:

[0295] Embodiment 1: The terminal requests the network device to send SIB 1, and / or indicates that the terminal expects or requests an RRC state in the first cell.

[0296] Step 1: The UE determines a target resource, which is the first resource or the second resource;

[0297] Taking the preamble (Msg 1) sent by the UE during the random access process to request the network device to send SIB 1, and / or indicate that the terminal expects or requests the RRC state in the first cell as an example, the target resource can specifically be a target PRACH resource, that is, the first resource is specifically a first PRACH resource, and the second resource is specifically a second PRACH resource.

[0298] The first resource or the first PRACH resource is a resource used by the UE to request SIB 1 and / or indicate that the terminal expects or requests the first RRC state in the first cell, where the terminal expects or requests the first RRC state in the first cell can also be called the terminal requesting to perform a connected mode operation (connected mode operation); the second resource or the second PRACH resource is a resource used by the UE to request SIB 1 and / or indicate that the terminal expects or requests the second RRC state in the first cell, where the terminal expects or requests the second RRC state in the first cell can also be called the terminal requesting to perform an idle and / or inactive mode operation (Idle / Inactive mode operation).

[0299] Step 2: The UE sends a preamble (Msg 1) on the target PRACH resource to request the network device to send SIB 1 and / or to indicate that the terminal expects or requests the RRC state in the first cell.

[0300] In step 1, the UE may determine the target PRACH resource based on the operation or behavior to be performed by the UE, which operation or behavior includes: connected mode operation and idle / inactive mode operation. For example, when the UE expects or requests the network device to send SIB 1 and performs connected mode operation, the UE determines the target PRACH resource to be the first PRACH resource; when the UE expects or requests the network device to send SIB 1 and performs idle / inactive mode operation, the UE determines the target PRACH resource to be the second PRACH resource.

[0301] In some embodiments, the case where the UE is to perform a Connected mode operation, or an operation related to the terminal being in a first RRC state in a first cell, includes but is not limited to at least one of the following:

[0302] The UE has data to transmit or receive;

[0303] The UE expects to receive a RAR message after receiving SIB 1;

[0304] The UE expects to enter the connected state for data transmission;

[0305] The UE expects to send Msg 3 after receiving SIB 1;

[0306] In some embodiments, the case where the UE is to perform an Idle / Inactive mode operation, or an operation related to the terminal being in the second RRC state in the first cell, includes but is not limited to at least one of the following:

[0307] The UE expects to stay in the first cell after receiving SIB 1, for example, to perform RRM measurement and receive paging messages in the first cell.

[0308] The specific process can be found in the embodiment of the information processing method on the terminal side described above. To avoid repetition, it will not be described here.

[0309] Optionally, when the network device sends SIB 1 based on the first information sent by the terminal, the SIB 1 may carry first indication information for indicating whether the UE is allowed to access the first cell, that is, the first indication information may indicate whether the UE can perform Connected mode operation in the first cell in which SIB 1 is obtained or perform operations related to the first cell being in the first RRC state, or the UE can perform Idle / Inactive mode operation in the first cell in which SIB 1 is obtained or perform operations related to the first cell being in the second RRC state by default. Alternatively, the UE may obtain the first indication information through other cells before sending the first information, and the embodiments of the present disclosure are not limited to this.

[0310] In some embodiments, if the first indication information is not carried in SIB 1, the UE can perform Connected mode operation or perform operations related to the first cell being in the first RRC state in the first cell in which SIB 1 is obtained by default, or the UE can perform Idle / Inactive mode operation or perform operations related to the first cell being in the second RRC state in the first cell in which SIB 1 is obtained by default.

[0311] In some embodiments, regardless of whether the SIB 1 carries the first indication information or whether the UE obtains the first indication information in advance through other cells, the UE directly defaults to being able to perform a Connected mode operation or perform operations related to the first cell being in the first RRC state in the first cell in which the SIB 1 is obtained, or the UE defaults to being able to perform an Idle / Inactive mode operation or perform operations related to the first cell being in the second RRC state in the first cell in which the SIB 1 is obtained.

[0312] Embodiment 2: Configuration or determination method of the first resource and the second resource.

[0313] Step 1: Taking the preamble (Msg 1) sent by the UE during the random access process to request the network device to send SIB 1 and / or indicate that the terminal expects or requests the RRC state in the first cell as an example, the UE determines that the target resource is a target PRACH resource. Accordingly, the first resource is a first PRACH resource, which is a resource used by the UE to request SIB 1 and / or indicate that the terminal expects or requests the first RRC state in the first cell; the second resource is a second PRACH resource, which is a resource used by the UE to request SIB 1 and / or indicate that the terminal expects or requests the second RRC state in the first cell.

[0314] Step 2: The UE sends a preamble (Msg1) on the target PRACH resource.

[0315] In some embodiments, the PRACH resource (ie, the first PRACH resource and / or the second PRACH resource) may be a resource for sending a preamble sequence, or a time domain resource and / or a frequency domain resource for sending a preamble.

[0316] Option 1: When the preamble is sent on the first PRACH resource and the second PRACH resource, the corresponding preamble sequences are different. In this case, the time domain resources and / or frequency domain resources corresponding to the first PRACH resource and the second PRACH resource may be the same or different.

[0317] The gNB uses the preamble sequence on the target PRACH resource to determine whether the UE needs to perform connected mode operation or idle / inactive mode operation after obtaining SIB 1.

[0318] In some embodiments, the preambles sent on the first PRACH resource and the second PRACH resource correspond to different preamble sequences, which may be performed in one of the following ways:

[0319] Method A1: The first PRACH resource determines the corresponding preamble sequence by a first index value, such as random access preamble start index 1 (ra-PreambleStartIndex_1); the second PRACH resource determines the corresponding preamble sequence by a second index value, such as random access preamble start index 2 (ra-PreambleStartIndex_2). The first index value is different from the second index value, or the first index value is not equal to the second index value, that is, the values ​​of ra-PreambleStartIndex_1 and ra-PreambleStartIndex_2 are different or unequal. In some embodiments, the first index value and the second index value can be configured by a network device or agreed upon by a protocol.

[0320] Method A2: The network device can be configured with an index value, such as ra-PreambleStartIndex_1;

[0321] For example, the index value can be used to determine the preamble sequence corresponding to the first PRACH resource. The first PRACH resource determines the corresponding preamble sequence through ra-PreambleStartIndex_1; the preamble sequence corresponding to the second PRACH resource is determined by ra-PreambleStartIndex_1 and a predefined rule or a first parameter. For example, the predefined rule is that the preamble sequence corresponding to the second PRACH resource is the sequence corresponding to ra-PreambleStartIndex_1+N.

[0322] For another example, the index value can also be used to determine the preamble sequence corresponding to the second PRACH resource. The second PRACH resource determines the corresponding preamble sequence through ra-PreambleStartIndex_1; the preamble sequence corresponding to the first PRACH resource is determined by ra-PreambleStartIndex_1 and a predefined rule or a first parameter. For example, the predefined rule is that the preamble sequence corresponding to the first PRACH resource is the sequence corresponding to ra-PreambleStartIndex_1+N.

[0323] Optionally, the value of N may be specified by the protocol or indicated by the first parameter.

[0324] Option 2: When the preamble is sent on the first PRACH resource and the second PRACH resource, the time domain resources and / or frequency domain resources corresponding to the first PRACH resource and the second PRACH resource are different (or the time domain resources and / or frequency domain resources do not overlap).

[0325] Optionally, the time domain resources corresponding to the first PRACH resource and the second PRACH resource are different (or the time domain resources do not overlap), and one of the following methods may be used:

[0326] Mode B1: The time domain resource corresponding to the first PRACH resource and the time domain resource corresponding to the second PRACH resource are different PRACH configuration periods, that is, the first PRACH resource corresponds to a first PRACH configuration period of at least two PRACH configuration periods, and the second PRACH resource corresponds to a second PRACH configuration period other than the first PRACH configuration period of the at least two PRACH configuration periods. For example, the network device may configure different PRACH configuration periods for the first PRACH resource and the second PRACH resource, such as configuring different PRACH configuration period indexes or configuring different other parameters for determining the PRACH configuration period.

[0327] Mode B2: The time domain resource corresponding to the first PRACH resource and the time domain resource corresponding to the second PRACH resource are different PRACH association periods, that is, the first PRACH resource corresponds to a first association period of at least two PRACH association periods, and the second PRACH resource corresponds to a second association period of the at least two PRACH association periods other than the first association period. For example, the network device can configure different association periods for the first PRACH resource and the second PRACH resource, such as configuring different association period indexes or configuring different other parameters for determining the PRACH association period;

[0328] Mode B3: The time domain resources corresponding to the first PRACH resource and the time domain resources corresponding to the second PRACH resource are ROs corresponding to different time periods in a PRACH configuration period, that is, the first resource includes the resource corresponding to the first time period in the PRACH configuration period, and the second resource includes the resource corresponding to the second time period in the PRACH configuration period.

[0329] In some embodiments, the unit of the different time periods (i.e., the first time period and / or the second time period) may be at least one of a frame, a subframe, a time slot, etc.; the network device may configure different time periods for the first PRACH resource and the second PRACH resource, for example, configuring at least one of the length of the different time periods, configuring the start time of the different time periods, configuring the end time of the different time periods, configuring the index of the different time periods, etc.;

[0330] Optionally, the frequency domain resources corresponding to the first PRACH resource and the second PRACH resource are different (or the frequency domain resources do not overlap), and the following manner may be adopted:

[0331] The frequency domain resources corresponding to the first PRACH resource and the frequency domain resources corresponding to the second PRACH resource are ROs on different frequency domain resources, that is, the RO on the frequency domain resource corresponding to the first PRACH resource does not overlap with the RO on the frequency domain resource corresponding to the second PRACH resource.

[0332] In an embodiment of the present disclosure, when a UE may have data to transmit and desires to enter a connected state through a random access procedure on an energy-saving cell to send uplink data, the UE determines a first PRACH resource as a target PRACH resource and sends a preamble to the energy-saving cell to trigger the transmission of SIB 1. After receiving the preamble on the first PRACH resource, the network device estimates the TA based on the preamble. This eliminates the need for the UE to use the preamble again after receiving SIB 1 for the network device to estimate the TA, thereby reducing the delay for the UE to enter the connected state and reducing signaling overhead.
